Here's a quote from the review page:
We both liked it because we’ve tried to incorporate a vibrator before and well, quite frankly, it’s too much to try and stick in there at one time and one or both of us has to get a hand on the vibe to keep it in, or the vibrator comes out and it’s just a hot mess. This little cutie solved that problem for us in a big way. Can I tell you how nice it is to be able to easily use a toy simultaneously with the real thing? Not to mention that hubby loved the fact that I now have a vibrating vagina! We both agreed that it didn’t distract or detract from the experience.So we’re kind of fond of the little We-Vibe, around here. It’s Very. Nice.
